Good product especially for the price. Great for races because it is small in size. Really keeps track of heartrate zones and cadence. Computer software gives a clear read of what you are doing. Also great for everyday riders to track their progress.

It is a very good unit for FS and MTB in general as I have never seen a computer with magnet that dont require 2mm of space while this goes up to 12mm. The sensors also have good range and fit on my AM bike fine. Lastly if you want a computer that will track every piece of info for you then get this; it even track the temperature while you ride.

Weaknesses: Rise rate computation is slow. The logger doesn't track instant cadence only average cadence. The software lacks long term analysis options. High learning curve on computer interface.

Bottom Line:

Number one on my list was a computer that displayed multiple pieces of information on the screen simultaneously. And by this ... I don't mean displaying average and total metrics at once. The Sigma packs 3 data lines of info, each independently configurable and the top will condense to display heartrate, cadence, altitude and rise rate simultaneously.

And of course, it records my ride and allows me to view it later. To help, the big button on the unit allows you to set waypoints so you can tag them later as being different locations on the trail.

The software is easy to use and is excellent for analyzing a single ride. However, there really is nothing in the software for long term analysis.

The learning curve on the software is a little steep but once you get used to it, it makes a LOT of sense. Despite the myriad of menus on the computer I can easily find them all. This compared to my Micro Wireless which I still forget how switch from one wheel to another due to only having two buttons.

Speaking of buttons, the Rox has 5 of them. They enable you to navigate menus with ease. There are only a couple of options that you have to "memorize", manual resync, backlight enabling and altitude synchronization.

Overall this is by far the most enabled bike computer in it's price range. It has everything but GPS. Some of the Polar unit's come close but fail at their small screens and pickups that don't allow you to replace the battery.

Finally, don't be tempted to go with the ROX 8.0. It does not have logging functions so it only records average values for a ride. Just get the 9.0.
